I'm Martin, from the UK, and I make mathematical art.
(mostly animations, almost always using @Desmos, and frequently inspired by the wonderful mathematical community on Twitter)

My daughter and I have been thoroughly enjoying Uncharted with @FryRsquared. Complex and intriguing subject matter expertly distilled into 15-minute chunks, each one linking data and graphs to the human stories behind them.

Hi! do you know who made this? I tried reverse searching on google images and found you instead. But can't seem to find this particular animation anywhere (I found this on 9gag months ago so can't trace the source anymore)

You knew it and you forgot to tell me ! :)
I made an animation in @GHSMaths style to illustrate the hinged dissection.

When the small squares are all congruent and the large squares are √(2+√2) times bigger, you get this pentagon. Four copies make a hinged dissection (square ⇆ regular octagon).

I was a bit surprised that you can post a Pringle through a letterbox-
because twisting straight lines trace out the hyperbolic paraboloid Pringle shape

It was so much fun to recreate these scenes from Series 5, and I’d love for others to enjoy it too (sound on for the video…).

we call x^2 “squared,” we call x^3 “cubed,” but people forget there’s a word for x^8 and that it’s zenzizenzizenzic
